You may frequently wonder where the “bleep” of these tiny fleas comes from. Whether it’s the first time you’ve had a flea problem or if it’s happened many times before, you will be surprised to notice them. It becomes even more astonishing when you get a flea infestation without pets. Keep reading to learn how fleas enter and hide inside a house without pets.

Why Do I Suddenly Have Fleas in My House?

There can be various reasons for fleas coming to your home. Some of the most common ones are discussed below.

A Gift from the Neighbors

A potential cause is your neighbor’s garden, particularly if they have pets that bark at the surrounding fence. I don’t advise you to go around checking their dog or cat or asking them about their pets. People assume you’re accusing them of negligence, based on my personal experience. Instead, line the fence with a row of cedar wood chips (approximately 2-3 feet wide) to keep fleas away.

Pets from the Past

Even in urban areas, fleas are more frequent in households with pets in the past. In the street, pets interact with one another and spread fleas to one another. Fleas are simple to catch at home because they attach to household linens such as curtains, sheets, towels, and carpets.

You can find yourself thinking, “Why are there fleas in my bed?” Flea eggs can fall and develop silently in every housing area, even though they live on our animals’ skin. If you have a problem with fleas in your house, we recommend reading our post on how to get rid of fleas in your home.

Rats or Squirrels

Even if you don’t have pets (in comparison to dog or cat owners), you might get fleas since they thrive on wild creatures, including rats, raccoons, squirrels, skunks, and possums. If these animals visit your yard, reside beneath your house, or even dwell on your roof, you will almost certainly receive a few fleas from them from time to time, and if left uncontrolled, this might lead to an infestation.

Where Do Fleas Hide in The House?

Even though flea larvae are born blind, they soon detect the fleas’ feces and organic materials, which serve as nourishment for the flea larvae. You’ll need to know where fleas reside and hide to manage them effectively. The saliva of the fleas prevents the host from detecting them right away.

Fleas will also hide in the cracks and crevices in the baseboards of hardwood floors. Fleas will build their nests as pesticides, and other flea control devices will be unable to reach them. The cracks and crevices provide safe havens away from any mechanical damage you might use to kill the bugs.

Carpets and Rugs

Fleas prefer to lay their eggs in rugs and carpets in homes and apartments. Female adult fleas lay about 50 eggs per day. Flea larvae eat the feces of adult fleas that have been left on the ground. As a result, the fleas will have an easy time surviving under the carpet because they will have a plentiful food supply.

Furthermore, fleas in the cocoon stage, which hide under the rug, are immune to pesticides, so you need to clean and vacuum the house regularly to get rid of them. Flea larvae will be found in carpet fibers. Furthermore, the flea larvae will be protected by the carpet canopy from various chemical, environmental, and mechanical threats. Furthermore, most modern carpets collect dirt, which provides ample food for the larvae.

Mattresses and Beds

Do you find it shocking and irritating to notice fleas on your carpet? It’s much more difficult when a flea bites your comfortable bed or mattress. Imagine mosquitoes biting you and feasting on your flesh and blood as you sleep.

Will Fleas Go Away On Their Own?

No, fleas will not go away on their own. Instead, you will need to follow some steps to get rid of the fleas mentioned below.

Avoid Country Homes

If you’re wondering, “why are there fleas in my house,” you should know that fleas in the home are more frequent in country homes than in metropolitan homes. This is because our pets are more likely to be in areas where fleas are abundant and transfer fleas into our yard. Fleas thrive in open spaces such as yards or gardens, which are then carried in by pets.

Manage Humidity

 If you want to avoid fleas at home, one of the essential elements is humidity. Because it is the most incredible setting for these parasites to meet and multiply, humidity is responsible for the nesting and proliferation of fleas at home. You’re more likely to get fleas if your home has little natural light and is wet. That is why I need to obtain as much sunshine as possible and use dehumidifiers to keep fleas out of my house.

 Fleas are also more likely to thrive in a home with inadequate hygiene. The most difficult to reach and clean areas of the house might become infection hot spots where fleas thrive and breed at home. If you’re wondering why you have fleas in your bed, you should realize that mattresses are particularly appealing to fleas since they contain a lot of filth and mites. To keep fleas at bay at home, ensure the mattress is kept as clean as possible.

Change Warm Climate Indoor

Flea infestations are more frequent in homes with a lot of heating and a warm climate (if it’s not dry). This is one of the reasons why fleas thrive in homes with carpets or rugs. Likewise, they will enjoy homes with many wigs. Keeping the climate of your home moderate can be quite beneficial to prevent flea attacks.
